I have a problem and am not sure just what the best remedy is. I have 4 chicks that are 11 weeks old. (posted pics a while back). 4 different breeds: BCM, BLRW, Barnvelder and Ameraucana. The BCM has pecked the back of the Ameraucana and the Barnvelder to the point of creating a sore/scab. Has not bothered the BLRW tho'. The chicks are in a penned area inside the gazebo where the 4 Columbian Wyandottes live. I have to get this resolved quickly before any more damage is done to the poor victims. Suggestions? Thanks I am going to take more pics....maybe the BCM is a roo after all??
